Development of an unconventional test method involves usually the comparison of biological responses under a variety of test conditions. The quality of these biological methods relies on an appropriate experimental design. The Daphnia magna heartbeat rate as a physiological endpoint for assessing aquatic pollution has been of minor interest so far; nonetheless, this could be an early and sensitive indicator of the harmful effect of micropollutants. Our aim was to set up the optimal experimental design of the heartbeat rate test. The studied factors were the composition of the test medium, the age of the test organism, and the exposure time, at triclosan concentrations between 0.2–2000 μg/L. According to the evaluation of test results the optimal test condition for the heartbeat rate test assumes tap water as test medium, 10-day-old test organisms and 48 h exposure time.

sebelum dan sesudah dibelajarkan menggunakan metode bermain peran pada anak kelompok A Tkk Thomas Aquino Tuka Tahun Ajaran 2018/2019. Jenis penelitian ini adalah penelitian Pre-Experimental Design dengan menggunakan desain penelitian One Group Pretest-Posttest Design. Populasi dalam penelitian ini adalah seluruh anak A3 Di Tkk Thomas Aquino Tuka Dalung, Sampel dalam penelitian ini adalah 27 anak yang terdiri dari 18 anak perempuan dan 9 anak laki-laki. Sampel diambil dengan menggunakan tehnik sampling Jenuh serta data kemampuan berbicara anak diperoleh dengan menggunakan metode non tes, selanjutnya dianalisis menggunakan rumus uji–t dependent t test. Berdasarkan hasil analisis yang dilakukan dengan menggunakan uji-t di peroleh thitung = 14,13 > ttabel= 2,056 dengan taraf signifikan 5% dan dk = 26, sehingga H0 ditolak dan Ha diterima, ini berarti terdapat perbedaan yang signifikan terhadap kemampuan berbicara pada anak kelompok A melalui kegiatan bermain peran di Tkk Thomas Aquino Tuka dalung Tahun ajaran 2018/2019. Adapun data kemampuan Berbicara anak menunjukkan nilai rata-rata pre-test sebesar 50,13, sedangkan nilai rata-rata post-test sebesar 79,76. Maka dapat disimpulkan bahwa, Metode bermain peran berpengaruh terhadap kemampuan berbicara anak kelompok A Tkk Thomas Aquino Tuka Dalung Tahun Ajaran 2018/2019. Berdasarkan hasil tersebut dapat disarankan kepada guru untuk lebih mengembangkan inovasi dalam menerapkan pembelajaran kontekstual melalui kegiatan bermain peran.Kata Kunci : Kemampuan Berbicara, Metode bermain peran, Pre-Experimental Design This study aims to acquaint the influence of speaking ability towards child pre-test and post-test of applying the Role-play method to the group A3 of Thomas Aquino Kindergarten, Tuka, batch 2018/2019. This study is a study Pre-Experimental Design with the research method of One Group Pre-test and Post-test Design. The population of this study were all of the students in group A3 of Thomas Aquino Kindergarten, Tuka. The sample of this study were 27 students who consist of 18 females and 9 males students. The sample was conducted by the Saturation Sampling method and the data of the speaking ability of a child was obtained by the non-test method, then analysed by the Paired-t dependent t-test. Based on the result of analysis which organised by the Paired-t method, has obtained t-count = 14,13 is greater than (t-table) = 2,056 with significant level 5% and (dk=26), the Null Hypothesis (Ho) is rejected and the Alternative Hypothesis (Ha) is accepted. It means that there is a significant difference of speaking ability towards students in group A3 of Thomas Aquino Kindergarten, Tuka, batch 2018/2019 by Role-play method. However, the data of speaking ability towards child shows the average of the pre-test is 50,13, meanwhile the average post-test is 79,76. It can be concluded that the Role-play method affects on speaking ability towards students group A3 of Thomas Aquino Kindergarten, Tuka, batch 2018/2019. Regarding that study, it can be suggested to the teachers to develop more innovations in applying for the contextual learning program by the Role-play method.keyword : Speaking Ability, Role-play Method, Pre-experimental design, One Group Pretest-Posttest Design

An experimental method has been developed at The Aerospace Corporation to determine the thermal conductance of moving bearings in vacuum. The test involves the measurement of thermal conductance of a single bearing under controlled inner race rotational speed, axial load, and thermal environment. Applications of interest include high-speed momentum wheels and flywheels. This paper covers the experimental method developed for this purpose and the techniques used to establish measurement uncertainty.
